Thank you for the information. I will give it a shot and see what happens!

I was able to boot up the server using another USB drive and I followed the link and recommendations. I have two additional questions: 1. I have identified the parity and cache drives, but I do not remember what order the rest of the drives was assigned. What impact will having these "wrong" have on the system? 2. I was running the Plex Docker, will this magically start working again, or will I need to rebuild this? Thanks again for the support and guidance.

Thank you for the responses. Sadly, I do not have anything from when it worked. I will review the linked guide and see what I am able to determine. I will be setting aside some time to learn about methods to be better prepared for the next time this happens!

I had something similar to this happen to me. Every day, a clean shutdown would be started at random times during the day and night. I reviewed logs daily and fought with this for about 2 week. I finally started by replacing the PSU. I replaced it and still had the same issues. Felt very defeated. With the server on, while tinkering in the case, I bumped a wire and a clean shut down happened. Started to dig further and the wire from the power button on the case to the mother board was loose. I think it would vibrate enough to "short" and act like the power button on the case we quickly pressed. I re-seated it and never had the problem again. Might not be your situation, but might be worth looking into. Good luck!

Hello, I am new to UNRAID and, during a power outage, I think my USB drive has failed. I attempted to plug the USB device into another computer, and it connects and disconnects many time, but never actually mounts. I do not have a backup of the drive (I will learn from this), and while researching how to replace this drive, the wiki.unraid states "you will need to make sure you assign each disk to the array / cache exactly as it was prior to the failure. If you do not know which disks were assigned where, create a post in the forum for further assistance." So I am posting to hopefully get some assistance. I am looking for any advice on how to properly assign the drives once I get a replacement USB drive up and running. Thank you!
